Studying the detailed structural and functional characterization of different types of glycans is essential to understand the mechanism of various biological activities and the pathology of several diseases. CD BioGlyco has been trying to develop simple and effective enzymatic methods to release glycans from complex biological samples. We expect to be your research assistant in the field of glycobiology.

Unlock Glycans: Enzymatic Release for Deeper Insights

Glycosylation is an important way of post-translational modification of proteins, which has a variety of biological functions, such as immune recognition, signal transduction, cell adhesion, and tumorigenesis. Therefore, the development of effective methods to release glycans from the protein backbone is of great significance to the study of their structure and function.

In contrast to chemical methods of glycan release, enzymatic release can be carried out with minimum instructions in any laboratory. In the past two decades, more and more enzymes including endoglycosidases and glycosidases have been reported to release glycans from glycoproteins under mild conditions. The endoglycosidase endo-β-N-acetylglucosaminidase H (Endo H), peptide-N4-(acetyl-β-glucosaminyl) asparagine amidase F (PNGase F), and PNGase A are the most preferred endoglycosidases, N-glycans can be conveniently and non-selectively released from glycoproteins using these enzymes.

Key Technologies

At CD BioGlyco, our glycan enzymatic release services are underpinned by a robust suite of core technologies designed for unparalleled specificity and efficiency. Our expertise lies in the strategic application of a comprehensive panel of highly purified glycosidases and glycoamidases. This includes industry-standard enzymes like PNGase F for the complete and gentle removal of N-linked glycans, as well as an extensive range of exoglycosidases and endoglycosidases optimized for specific glycan linkages and structures. We leverage proprietary enzymatic blends and optimized reaction conditions that are tailored to the unique characteristics of each sample, ensuring maximum glycan release yield with minimal degradation or structural alteration. Our advanced enzymatic platforms are complemented by state-of-the-art analytical instrumentation, allowing for precise monitoring of the release process and immediate preparation for subsequent analytical workflows.

Comprehensive Glycan Release: Tailored Solutions for Every Glycosylation Need

Enzymes are useful for the structural analysis of glycans and polysaccharides and for establishing structure-activity relationships in biological systems. To better characterize glycans on proteins, CD BioGlyco has developed an advanced glycan enzymatic release platform. We provide efficient and accurate release services of N-glycan, fucose, galactose, N-acetylgalactosamine (GalNAc), O-glycosylated protein, core-1 O-glycan, and sialic acid for our clients.

Applications

• Biopharmaceutical development and quality control: In the biopharmaceutical industry, glycosylation significantly impacts the efficacy, immunogenicity, and stability of therapeutic proteins (e.g., antibodies, enzymes). Enzymatic glycan release is crucial for detailed characterization of glycosylation patterns, enabling comparability studies, biosimilar development, and routine quality control to ensure product safety and potency.
• Biomarker discovery: Altered glycosylation is a hallmark of numerous diseases, including cancer, inflammatory conditions, and infectious diseases. By enabling precise glycan profiling, enzymatic release facilitates the discovery of novel glycan biomarkers for early disease detection.
• Vaccine development: Glycans on pathogens often serve as key targets for immune recognition. Understanding the glycosylation of vaccine antigens through enzymatic release and subsequent analysis is vital for designing more effective vaccines that elicit robust and targeted immune responses.
• Fundamental glycobiology research: Enzymatic glycan release is a foundational technique for elucidating the roles of glycans in various biological processes, including cell signaling, cell adhesion, development, and immunity. It allows for the precise investigation of glycan structure-function relationships.
